HRC70 Square Carbide End Mill | High-Performance CNC Cutter for Titanium, Inconel & Hard Steel - Changzhou QT TOOLS

Product Function

Our HRC70 Square Carbide End Mill is engineered for the most demanding CNC milling operations. Designed primarily for side milling, slotting, and profile milling, this tool excels in removing material efficiently while maintaining exceptional dimensional stability. It is the ideal solution for machinists needing to cut extremely hard materials or difficult-to-machine superalloys without frequent tool changes.

Product Features

Superior Hardness (HRC70): Made from ultra-fine micro-grain tungsten carbide, offering exceptional wear resistance and rigidity.

Special Advanced Coating: Features a proprietary high-heat resistant coating that reduces friction and prevents built-up edge (BUE), crucial for machining sticky materials like Titanium and Stainless Steel.

Wide Material Applicability: Perfectly suited for Titanium Alloys, Heat-Resistant Superalloys (Inconel), Stainless Steel (304/316), Mold Steel, and Hardened Carbon Steel.

Vibration Absorption: The flute geometry is optimized to minimize vibration and chatter, ensuring a superior surface finish.

Extended Reach Options: Available in standard lengths and extra-long series (up to 150mm) for deep cavity machining.

FAQ

Q1: Can this HRC70 end mill cut Aluminum? A: While it is hard enough, we do not recommend it. This tool has a coating designed for heat resistance in hard metals. For Aluminum, we recommend our uncoated or DLC-coated bright finish end mills to prevent sticking.

Q2: What is the delivery time for the items in the specification table? A: All items listed in the table are currently in stock. Orders usually ship within 24-48 hours after payment confirmation.

Q3: Do you offer OEM/ODM services? A: Yes, we can manufacture custom tools based on your drawings or specific requirements (e.g., different shank diameters, corner radius, or taper angles).

Q4: What shipping methods do you use? A: We typically use DHL, FedEx, UPS, or TNT for fast delivery (3-7 days). We can also use your shipping account if preferred.
